hello mate..
Mass of sodium chloride = 36 g
Mass of solution = 36 + 100 = 136 g
Concentration of solution
= mass of solute/ mass of solution ×100
= 36/136 × 100 = 26.47% (w/w)
please mark this answer as brainliest and follow me too

Answer:
Mass of sodium chloride=36g
Mass of solvent=100g
Mass of sollution=mass of solute + mass of solvent
=36g + 100g=136g
Concentration of solution=mass of solvent÷mass of solution×100
=36÷136×100
3600÷136
=26.47%
Hope this will help plz if u like this answer then add it to brainlist plz and thanks to
